Description

English: 1=The flock of Chapman Swifts swirling into a 1920s elementary school chimney to roost for the night. These Vaux's Swifts (Chaetura vauxi) are quite selective about their roost during their annual migration from the Pacific Northwest to Central America. They spend about four weeks in the Portland, Oregon area each autumn.
